ROSS TAYLOR, OF NEW YORK, N. Y., ASSIGNOR TO AUTOMATIC VENTI- LATOR COMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK.

VENTILATOR.

SPECIFICATION forming part of Letters Patent No. 793,404, dated June 27, 1905.

Application filed September 14, 1904. Serial No. 224,395.

To all whom, it may concern:

Be it known that I, Ross TAYLOR, a citizen of the United States, residing at New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Ventilators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to certain new and useful improvements in ventilators, and more particularly to that class known as house-ventilators, which are usually located within a window and of that type embodying the injector and ejector principle of operation.

' My invention has for its object to provide a ventilator of the character described which shall be simple and economic of construction and which shall be especially adapted to arrest, divide, and take in currents of air traveling in varying planes and to vertically divide such air into a series of columns and deflect them in an upward direction into the apartment to be ventilated, while at the same time permitting the vitiated air in said compartment to escape therefrom in a lower and different plane from the ingoing air.

With these ends in view my invention consists in the details of construction and arrangement hereinafter more fully described.

In order that those skilled in the artto which my invention appertains may know how to make and use the same and fully appreciate all of its advantages, I will proceed to describe my improved ventilator, referring by numerals to the accompanying drawings, in which Figure 1 is a perspective view, partially broken away, of a ventilator embodying the features of my invention. Fig. 2 is a hori zontal section taken on the line a (6 and looking downward. Fig. 3 is a vertical detail section on the line b 5 looking in the direction of the arrow. Fig. 4 is a transverse central section on the line 0 0 looking to the right. Fig. 5 is an elevation showing the manner of applying my improved ventilator to a Window between the sill and the lower rail of the sash, and Fig. 6 is a similar view showing the ventilator installed directly within the glass of a window.

Similar reference-numerals indicate like parts in the several figures of the drawings.

1 is the top, and 2 the bottom,which are preferably made of sheet metal, and 3 3 are the L- shaped ends, which are secured by rivets 4. or in any other suitable manner to flanges 5 at the ends of the top and bottom parts 1 2. The top and bottom are each of triangular shape, as clearly shown. and arranged vertically between them are a series of parallel sheet-metal louvers or air-dividing plates 6, formed at each end with flanges 7, which are secured by rivets 8 to the said top and bottom portions. The top 1 is preferably formed with longitudinal flange 8, designed to give additional strength and rigidity to the structure.

The louvers or plates 6 incline in opposite directions each side of the center, as clearly shown in Fig. 2, and the ventilator is divided into two separate compartments by centrallydisposed dish-shaped d eflector-plates 9, formed with flanges 10 and secured by rivets 11 to the top and bottom portions 1 2. These dishshaped deflector plates 9 are separated, as clearly shown at Fig. 2, to constitute a space between them for the purpose presently explained. This space is closed at the outer side by a suitable narrow strip or plate 12 and on the inside, on each side thereof, are secured vertical strengtheningstrips 13, which may be independent of or formed with the top 1, or in lieu of these strips 13 the rear edges of the deflector-plates may be flanged outwardly.

Hinged at 14 to the bottom 2 are two interior deflector-doors 15, the adjacent ends of which are returned and of quadrant form, as shown at 16, and which have their upper edge formed with a series of depressions or notches 17 adapted to receive the projections on the under side of the free end of a split or bifurcated spring 18, which is riveted at 19 to the under side of the top 1. The ends of the deflector-doors 15 are located within the space between the two outside deflectors 9, and said doors may be opened or closed to any desired extent and held in position by the spring 18 in an obvious manner. The doors 15 are equipped with a suitable operating-handle 20.

While I prefer to construct my improved ventilator entirely of sheet metal, I do not wish to be confined to any especial material.

When used in an ordinary window either between the lower rail of the sash and the sill or between the upper rail of the sash and the window-frame, the ventilator is suitably secured within an opening of a board or frame, as clearly shown in Fig. 5, adapted to occupy the space within which the ventilator is to be located.

When it is desired to install the ventilator within the glass of a window, a rectangular opening is cut through the glass corresponding with the outline of ventilator, and the latter is provided at each end with a flange 21, (shown in dotted lines, Fig. 2,) which may be bolted to the glass, and to avoid the passage of any air between the ventilator and the glass ordinary weather-strips may be employed, as illustrated at Fig. 6, in which 22 represents the weather-strips, and 27 the securing-bolt.

From the construction shown it will be seen that any current of air passing in either direction across either of the oblique faces of the ventilator extending outwardly from the window will be intercepted by the several vertical deflecting-plates or louvers 6 and one of the central deflectors 9 and directed to the interior of the apartment. The interior deflector-door 15 on that side of the ventilator where the pure air enters being adjusted, as illustrated at the right-hand end of Fig. 1, will cause the ingoing current to be deflected upward and toward the ceiling of the apartment in a plane determined by the angle at which the door 15 is set. The door at the opposite end is opened to a greater extent than the other, and the vitiated air which is forced downwardly by the pure air will enter the ejector end of the ventilator at a plane lower than that at which the pure air is injected, and hence disagreeable drafts will be avoided. The dish-shaped deflectors 9 divide the ventilator into two separate and independent compartments, and hence as the current of air passes across the ventilator part of it is caught and injected into the apartment or room, While the remainder passing onward beyond the central dish-shaped deflectors produces a partial exhaust, which, cooperating with the downward pressure exerted upon the vitiated air within the apartment or room by the injected pure air, causes the latter to be ejected.

The quadrant ends 16 of the adjustablev doors 15 prevent the ingoi'ng and outgoing air from intermingling and escaping together. The arrows in the several figures of the drawings indicate the paths of the air-currents.

Having describedthe construction and operation of my improved ventilator, what I claim as new, and desire to secure by Letters Patent, is

1. A ventilator consisting ofa triangular casing open at its front and rear; centrallydisposed vertical deflectors at right angles to the inner straight face of the casing; a multiplicity of vertical louvers or deflectors intermediate the central deflectors and each end of the casing and secured at right angles to the exterior oppositely-inclined edges of the easing; adjustable deflector-doors hinged to the inner edge of the bottom of the casing and having their adjacent ends returned to form separating-partitions, and means for securing said doors in varying adjusted positions, substantially as hereinbefore set forth.

2. A ventilator for buildings consisting of triangular-shaped top and bottom plates diminishing in width from the center toward each end and secured together by vertical end pieces; vertical parallel fixed louvers arranged at right angles to the outer edges of top and bottom plates; centrally-located dish-shaped deflector-plates between the adjacent oppositely-inclined sets of louvers, secured in position to produce a space between said deflector-plates; adjustable deflector-doors hinged to the inner edge of the bottom and havingadjacent quadrant ends located within the space between the two dish-shaped deflectors and having the curved edges formed with depressions or recesses, and a spring secured at one end to the under side of the top and having its free end adapted to interlock with the depressions or recesses in the curved edges of the door ends, substantially as and for the purpose set forth.

3. In a ventilator such as described, a par-' allel triangular-shaped casing consisting of top and bottom plates secured together at each end by. end pieces; centrally-disposed dish-shaped deflectors dividing the easing into two separate chambers; a series of vertical louvers in each chamber arranged in parallelism and inclined in opposite directions; and interior adjustable deflector-doors hinged to the bottom of the casing and having their adjacent ends returned, substantially as hereinbefore set forth.

4:. In a ventilator such as described, in combination with the casing divided into separate chambers by centrally-arranged vertical deflectors, and hinged and adjustable interior deflector-doors, having adjacent quadrant ends with depressions or recesses in their curved edges, a bifurcated spring secured at one end to this specification in the presence of two subto the under side of the top of the casing and scribing Witnesses.

having its free ends formed with a projection adapted to interlock with the depressions or ROSS TAYLOR 5 recesses in the ends of the deflector-doors, sub- Witnesses:

stantially as hereinbefore set forth. WALTER ARMITAGE, Intestimony whereoflhavesigned myname M. B. MEEHAN.
